Can Saxenda affect your period?

Weight loss can sometimes affect menstrual cycles, and Saxenda may contribute to temporary changes as weight reduces. Rapid or significant weight loss can lead to irregular periods or missed cycles. As weight stabilises, periods often become more regular.

You should seek medical advice if:

• Your periods suddenly become irregular and you are under 45
• There is a difference of 20 days or more between your shortest and longest cycles
• Your cycle occurs more frequently than every 21 days
• Your cycle is longer than 35 days
• Bleeding lasts longer than 7 days
